Hello, After installing Snow Leopard and I received the following warning when trying to run "sudo periodic daily weekly monthly" in Terminal: WARNING: Improper use of the sudo command could lead to data loss or the deletion of important system files. Please double-check your typing when using sudo. Type "man sudo" for more information. To proceed, enter your password, or type Ctrl-C to abort. Password: Did the command change for maintenance Scripts? I just want to make sure before creating problems with my system. I try to run the scripts every weekend due to not leaving my Mac Pro powered 24/7. Thanks for the help and advice.
